Mac Geekery

Ok heres the deal my school has individual laptops for every student and we have some preferences locked and i went in through single user mode and made a new account with admin and got caught did it again and this time idk wat they gonna do they got my comp. But the deal is the tech man is isntalling a software er sumtin to prev ent users from logging in using single user mode in their anyway to get past it or negate it??? if there is sucha thing it might just be a bunch of bull but i dont know.

i m the mom of the youngest of 3, a 17 yr old who is cracking all my password efforts.
i would change the password for his account sign on, as well as my own password, to
control how much he is on my imac when he does not do well in school. over the last
couple of days, i changed the passwords twice and found him on anyway. when asking
him how he is doing this, his reply is “i know at least 3 ways to get around your password
changes”. heck i don’t and i thought if the admin changes an accounts password, then
locks up the changes, that was that. any suggests to really lock him out when i need to?

So I want to make text ads on the site available at a price that the everyday goon can advertise whatever he wants with them (his blog, his Mac autopsy, whatever).

I’m leaning towards $5 for 1,000 impressions and/or $25/week.

Too much, too little? I have some filler in there now to see how fast it runs through, but I would expect them to be about equal.
